does build_scripts cover "tee-xxx.srec"

[jiedummy]

The build_scripts is very helpful tool. It looks like it does not cover "tee-xxx.srec". Is there any method to generate "tee-xxx.srec" outside of yocto build system?

It probably can be done, but I have not tried. Most people use these scripts when porting BSP code to a new board doing some debugging. It is much easier to do that outside of Yocto. So in that case, you might not concerned about security features yet. That is the only reason why there is no build code for tee yet.

RZ/G2L example, parameters may need to be adjusted:

git clone https://github.com/renesas-rz/rzg_optee-os.git
cd rzg_optee-os
git checkout f9a0900230a5341d9a83799dab89f08f65840458
patch -p1 < 0001-hw_get_random_bytes-SUPPORT.patch
make -j 8 PLATFORM=rz PLATFORM_FLAVOR=g2l_smarc_2 CFG_ARM64_core=y CFG_REE_FS=y CFG_RPMB_FS=n CFG_CRYPTO_WITH_CE=n CFG_RZ_SCE=y CROSS_COMPILE64=aarch64-none-elf- ARCH=arm CFG_RZ_SCE_LIB_DIR=~/rz_secprv/smarc-rzg2l/Lib/

The patch and the lib (CFG_RZ_SCE_LIB_DIR) are in the security package.
